sz claim. (c1. oss-1s) This invention relates to laundary machines andhas special reference to that type of machine wherein miscellaneouslaundry articles are washed and the excess liquid extractedcentrifugally in a single container. The main objects of the inventionare: the provision of a new and improved mode of mounting the casing andattaching the operating mechanism thereto so as to permit the use ofenameled metal for the casing without danger of either 4cracking theenamel or leakage of liquid; the provision of a new mode of mounting thecasing, operating mechanism, and motor; and the provision?f of new,improved and simplified mechanism for raising and lowering the clothescontainer and its contents as required for the extracting and washingoperations respectively by the power of the same prime mover whichfurnishes the power for the extracting and washing operations. Otherobjects of the invention relate to the provision of an improved andsimplied operating mechanism; an improved and simplied arrangement forconnecting the mechanism to and disconnecting it from the clothingcontainer; the provision of improved means for starting and stopping therotation of the container; the provision of new and improvedconstruction of tub or outer casing; the provision of a new rinse-band;the provision of a new and simpliiled safety means for preventingextracting with the cover absent; the provision of a new brake; whilefurther objects and advantages of my invention will become apparent asthe description proceeds.

It should beunderstood that not all the improvements herein describedare limited to a device wherein Athe clothes-container has a verticalmovement;

In the drawings accompanying and forming a part of this application Ihave shown two specific embodiments of my inventive idea, although itwill be understood that these drawings are intended to be illustrativerather than limiting. Figs. 1`` and 2 are vertical central sectionalviews through4 that type of my improved machine wherein theclothes-container is raised and lowered between extracting and washingpositions, these corresponding to the lines I I and 2 2 respectively ofFig. 4 and theparts being in Washing position. Fig. 1 is a perspectiveview of the lsupporting plate; Fig. 3 is a sectional view similar toFig. 2 except that the parts are shown in extracting and rinsingposition; Fig. 4 is a horizontal sectional view corresponding to thebroken` line 4 4 01 Figs. 1,

Describing the parts by reference characters, I represents the uprightside-wall of a metal casing, preferably of enameled sheet metal, havinga water-retaining bottom formed with a flat annular portion 2mergingwith said side-wall and an elevated central portion 3 joined to theportion 2 by a slanting 'part 4 and itself having a central aperture 5.The top rim of the sidewall is preferably bent outwardly as shown at 6to form a peripheral reinforcing flange, and is also best provided withat least one circumferential corrugation 'l adjacent thereto to affordadded stiffness, andto trap splashing liquid. The portion 2 of the -tubconstitutes a seat and rests on the packing B carried by thecircumferential ilange 9 of the supporting plate indicated generally atl0. 'Ihis plate is preferably made of a single casting, circular inplan, but wavy in cross-section and formed with' an oblong opening ilwhich extends from a point near one margin to a point slightly beyondthe center. AThe wavy-character of the plate affords a sinuous marginVto this opening as shown in Fig. 1", certain portions indicated at l2being thereby located at a diierent level from other portions I3, andthese portions being formed with apertures I4 and I5 respectively. Thisopening il serves for the reception of the gearbox hereinafterdescribed, the shape of theplate exhibiting the double function ofstiffening the same and of enabling the gear-box to be attached atdifferent levels whereby it is the. more rigidly braced as willhereafter appear.

In addition to the characteristics already mentioned this plate is.preferably formed with a plurality (preferably three) ofdownwardlyfacing circular seats I6 closely inside its periphery, each of'these seats being deilned by an upwardly-extending boss I1 having acentral aperture I8 and located in contact with each seat is acylindrical, axially bored block 20 of soft rubber.

' Below and concentric with the plate I0 is a second rigid metal platehaving a peripheral depending iiange 2I merging'with a circular flange22 immediately inside the same and terminating in an inwardly-projectinghorizontal web 23 to whichl are secured the upper ends of the legs 24.The foregoing structure constitutes the supporting frame of the machine.Formed on the plate 23 are spaced seats 25 registering with the seats I6and supporting the opposite ends of the blocks 20. Theseats I6 and 25are apertured centrally in register with the axial bores oi' the blocks20 to receive the rope-connections 26 held in place by knots 21 at theirends, suitable cupwashers 28 being preferably provided for said knots.The casing is secured to said plate Ill by a plurality of screws 29located in holes formed at spaced intervals in the portion 9.

All the operating mechanism of the machine is preferably carried by asingle cast-metal block of rectangular form which ts inside the openingII and constitutes the upper end of the gearboxheretofore mentioned.This block comprises a rectangular depending skirt 30 terminating at itslower end in a flange 3| and closed at the top by a horizontal web 32formed with the upwardly extending, hollow, internally-threaded boss 33concentric with the casing and having studs 34 and A35 and 36 dependinginside the flange 30. This block is secured to the plate IU by suitablescrews 31 located in the apertures I4 and I; and screwed into the boss33 is a vertical, hollow bearing-sleeve 40 which projects through theaperture 5 into the interior of the casing to the desired height. A ring42 of soft packing surrounds the aperture 5 on each face of thecasing-bottom, and is backed up by suitable nuts (or washers) 4I screwedon the sleeve or otherwise held at proper height. These rings serve onlyto prevent leakage, Vwithout supporting function and hence without suchstrain as would crack the enamel when that kind of material is used, orproduce leakage` or deformation when copper is employed.

Slidably and rotatably mounted inside the sleeve 40 is a verticaldrive-shaft 44 having at its upper end an extension 45 of reduceddiameter surrounded by an abrupt shoulder 46 and itself terminating in aprismatic portion 41. Slidably and rotatably sleeved about the exteriorof that portion of the sleeve 40 which is located inside the casing I isa second sleeve 48 formed at its upper end with an internal flange 49which overlaps the upper lend of the sleeve 40 and the shoulder 46,being pierced by an aperture through which the extension 45 is freelymovable. Formed on the exterior of the sleeve 48, adjacent to its lowerend, are a plurality of vertical ribs 50 and also, spaced above theupper ends of said vertical ribs, a plurality of angular-lyspaced,arcuate, horizontal ribs 5I.

The clothes-container comprises an upright wall 52 located inside thewall I and defined by a surface of revolution about a vertical hollowhub 53 which surrounds and is spaced from the lower end of the sleeve48. Integral with the vare formed in the bottom 55.

upper end of this hub, and flaring outwardly and downwardly therefrom,is a pileus-shaped flange 54 to which is fastened the inner margin.- ofthe sheet-metal bottom 55 of this container, the outer margin of whichmerges with theI wall 52. l

The' wall 52 preferably ilares upwardly to. a point well above thebottom where it is seamed to an inwardly-tapering ledge 56 whichterminates in a rolled rim 51. This seam 58 affords reinforcementagainst bursting strains caused by rotation, while the inwardly-slopingledge prevents centrifugal ejection of the clothing Apertures 60 for thecentrifugal discharge of the liquid portion of the contents arenecessarily provided at the level of maximum diameter which is hereadjacent to the seam 58, and other apertures 6| for the ingress ofwashing liquid Whether additional apertures are provided in thiscontainer, is, in the form of this invention, shown in Figs. l to 3optional with'the manufacturer.

It is perfectly possible, and within my invention, to have the hub 53iit snugly over the sleeve 48 and omit the vertical ribs 50 thereof, butthere are-certain practical advantages concerned with the centrifugaloperation in spacing this hub from the sleeve and interposing in theresulting space some yielding supporting devices capable of permittingsuch a lateral displacement of the container as to compensate, in partat least, for an unbalanced condition of the articles therein. 'I'hesimplest expedient is to interpose rectangular soft-rubber blocks 52between these elements, the interior of the hub 53 being provided withvertical, integral ribs 64 intermediate the ribs 50 of `the sleeve,thereby producing the necessary driving function.

Loosely surrounding the sleeve 48 is a third hollow, cylindrical, sleeve65 having at its upper end an inwardly-turned flange 66 which terminatesin a prismatic socket 61 which engages the complementary portion 41 ofthe shaft. I have shown a. screw 68 located in the top of the shaft tohold this sleeve in engagement therewith although the same is not alwaysnecessary. Integral with the lower end of the sleeve 65 and flaringoutwardly and downwardly therefrom is a skirt 69 which terminates in acircular margin at a point intermediate the top and bottom of thecentral elevation with which the bottom of the container is providedaccording to the construction heretofore described; and merging with thesleeve and skirt are a plurality of radial blades 1| of any desirablenumber, here represented as three.

Formed in the lower end of the sleeve 65, immediately above the skirt69, is anl annular recess 12 in which the horizontal ribs 5I are looselyreceived when both sleeves 48 and 65 occupy their lowermost positions.The interior of said recess is formed at a lower level withinwardlyprojecting arcuate flanges .13 spaced apart angularlysuiliciently to enable the ribs 5I to pass between the same asillustrated in Fig. 8.

In the form of the invention shown in Figs. 1 to 7 the mechanism foroperating the shaft 44 is as follows: Loosely journaled around saidshaft inside the gear-box is a spiral gear 15,

' supported at a xed height in any suitable manl 2,067,572 itsprotruding end a belt-pulley The studv 34 is fo'med, as shown in Fig. 5,with an extension 82 of reduced size at its lower end, on whichextension is journaled the hub 83 of a wormgear 84 which meshes with asecond spiral-gear or worm 85 also carried by the same drive-shaft 19'.The web of the gear 84 is recessed above to a kind of basin-shape andlined with' frictionmaterial 06, while an eccentric pin, 01' projectingfrom its lower face has articulated thereto a pitman 88 whose oppositeend is articulated to anarm 89 projecting from the upper end of a sleeve90 journaled on the stud 35 heretofore mentioned. From the lower end ofthe sleeve 90 projects a second arm 9| which terminates ini an arcuatetoothed segment 92 which swings near the shaft 44.

Tightly secured to the lower end of said shaft is a metal block 93having a frusto-conical surface and surrounded by a toothed pinion 94adapted vto mesh with the segment' 92 and recessed to complement theshape of the block 93. Suitable friction material is interposed betweenthe adjacent surfaces of these parts and a suitable spring 95 carried bythe one serves to press the other yieldingly into contact therewith,while the adjacent faces of the gears 15 and 94 arer formed withprojecting teeth 96 for a purpose to be hereafter described. y

Rotatably journaled on the larger portion of the stud 34 is acylindrical cord-reel |00 having at its lower end an enlarged, integral,tapered flange |0| fitting inside the friction material heretoforedescribed and having at its upper end a second flange |02 surrounded bya brake-band |03. A volute spring |04 located within the hollowed-outflange 0| normally elevates the same out of driven-engagement, andloosely surrounding the stud 34 inside the hollowed-out flange |02 aretwo ring washers |05 and |06,'both formed with cam-projections |01 ontheir adjacenty surfaces. example |06, is held against rotation by thefixed pin |08, while the other is provided with a radial arm |09terminating in gear-teeth ||0 which mesh with other teeth carriedv bythe inner end of the horizontal rock-shaft ||2 journaled in one wall ofthe skirt 30. The outer end of this rock-shaft is provided with asuitable operating-handle ||3.

'The lower end of the shaft 44 projects beyond the gear 94 and isstepped in a hollow socket ||5 formed in the yoke IIS, said socket beingprovided with a suitable thrust-bearing ||1. The ends of this yokeproject laterally beyond the pulley 94 where they slidably engage thevertical rods ||0 carried by the studs 36 heretofore mentioned.Journaledon the yoke IIE are two groo'ved pulley-sheaves'i20 and carriedby the top-plate 32` is a third pulley'sheave |2|. A flexible cord |22has one end secured to the plate 32 whence it depends vertically',passes beneath the sheaves |20, |20, and over the sheave |2| whence itleads to theA reel |00. 1f, therefore, t'ne lever ||3 be rocked in theappropriate direction the resulting wedging action of the two camwashers forces the flange |0| into contact with the friction-lining ofthe gear 84, whereby the cord |22 is wound upon the reel and the yoke||6 elevated, carrying with it the shaft 44, and giving rise to thefollowing events:

The pinion 94 is disengaged from the segment 92 and the previousoscillating movement of the shaft is stopped although the segment stillcontinues to oseillate; `and upon arriving at the One of 'these washers,as for upper end of its path the pinion 94 is brought into contact withthe pinion 15 and partakes of its rotational movement by reason of theinterengagement of the teeth 96, thereby imparting rotation to thecontainer 52, rst gradually and thereafter with constantly acceleratingspeed due to friction-displacement of the pinion 94 about the member 93.At the same time the upward movement of the shaft 44 has served toelevate the sleeve 65 relative to the sleeve 48; if vby chance, the ribs5| coincided at the moment with the spaces between the anges 13, asshown in Fig. 8, this relative movement continues until the shoulder 48comes into contact with the flange 49 of the sleeve 40. and lifts thecontainer also, the ribs 5| being at this instant in the same plane withthe anges 13 as shown in Fig. 3; if, however, `as morefrequentlyhappens, this exact registry does not exist at the moment,

'then the tendency is to lift the containerl through theinter-engagement of the ribs 5|,` and flanges tainer also accompanyingthe rotational movement of the shaft when the same commences.

'Ihe function of the brake-band |03 is to hold the shaft and containerin elevated position. One end of this brake-band is secured to a fixedpin |25, and the other end to a movable pi n |26 carried by the end ofthe swinging lever |21 located near the' teeth and normally urged by aspring |28 in a direction to cause engagement of the brake-band. Thecord is wound on the reel in such `a direction that its unwindingtendency shall be to rotate the flange |02 in the direction shown by thearrow a in Figs. 6 and 7, which is that direction which coincides withthe gripping movement of the brake-band. As a result a sort4 ofratchet-action is produced which causes `the container to remainsuspended at any point to whichit is carried by the mechanism. Wheneverthe operator desires to lower the container the handle ||3 is tipped inthe opposite direction so as to cause the teeth or other suitableprojection, to engage the lever'|2|, and disengage this brake-band,whereupon the shaft and container sink gradually of their own weight,and the dasher recommences its motion of oscillation. Too rapid downwardmovement of the container may be readily checked by movement of thehandle ||3 ina direction to effect engagement of the brake band |03 withthe flange |02.

It is desirable that provisions be made to enable rinsing of theclothing in the container 52 without contaminating the washing liquidremaining in the casing I; and it is also desirable thatsafety-provisions be made to prevent, or'at least dissuade, theextracting operation unless and until the tub is completely covered topre'- vent any possibility of injury to the operator. These twofunctions may conveniently be performed by the following: tted to theupper part of the casing is a rinse band which, in its preferableconstruction, comprises an upright, cylindrical, metal strip |30 formedmidway of its height with an inwardly displaced.- corrugation |3|defining an outwardly facing groove in which is tightly soldered theinturned flange |32 of a second larger cylindrical band |33, vwhichprojects above the top of the strip |30. The lower end of the strip |30fits inside the casing the flange |32 resting on the flange 6. The band|33 defines an annular gutter |34 which is provided with a drainage cock|35, independ-l ent of the drainage cock |36 with which the casing isprovided. The tops of the strip |30 and of the band |33 are preferablyfolded, wired. rolled, or otherwise stiened, and the height of the band|33 is such as to terminate above the level of the strip |30 but belowthe level of the apertures 60 when the container is elevated intoextracting position, thus rendering it necessary for the operator tomaintain the cover in place while extracting is going on. This cover,preferably, is Ymade of Sheet metal having a cylindrical portion |40 tofit inside the band |33: a rib |4| to rest on top of said band; adome-shaped part |42 to surround the top part of the container; and a.central elevation |43 like a sort of cupola., formed in its side with aplurality of apertures |44 for the double purpose of admitting light,enabling inspection, and

permitting the introduction of a hose |45 for rinse-water as shown inFig. 3. One or more hand-grips |46 may be provided at any convenientpoint. To assist in arresting the rotation of the container I show brakeshoes |41, consisting of leather flaps mounted inside the cover andadapted to be pressed against the container by pushing against suitableknobs |48 which project through the cover.

In the preferred form of the invention the apertures 6| are restrictedwithin the limits of the circle defined by the inner margin of the rim51; also it is desirable, though not necessary, that the apertures 60 bemade rather` small; although whatever the size of these apertures, theywill generally become considerably impeded by the clothing during theextracting operation, with the result that when rinse-water isintroduced during the rapid rotation of the container, such. liquid willtend to become piled up around the outer wall of the container as shownin Fig. 3, and thus subject the clothing to a thorough rinsing action.By Vconfining the apertures 6| to the inner portion of the tubbottom,space is afforded for a substantial amount of rinsing liquid, althougheven if such an excess of rinse Water be supplied as to cause some toescape by these apertures, the upwardiy slanting shape of the containercauses much of it to climb to the seam 58 along the outside of the wall52 before being thrown off.

'Ihe mechanism is driven from the shaft |53 of an electric motor |54which is carried by that part of the frame having the flanges 2|, 22 andlegs 24. This being insulated from the casing and its adjuncts by therubber cushions 20, it is only necessary to employ an electricallynonconducting power transmitting device to have the motor whollyinsulated from the casingand operating parts. An example of such anonconducting power-transmitting element is the belt by which the beltpulley 8| of the shaft 13 is connected to the 'pulley |52 carried by theshaft |53. The base |55 of this motor is preferably attached to a plate|56 which is hinged to the plate 23 on a horizontal axle |51 which isparallel to the shaft |53 and its base is thus grounded through theplate 23 and legs 24 of the machine. A bolt |58 secured inside one ofthe legs 24 and provided with a thumbnut |53, serves to rotate the motorabout the axle |51 and thus tighten the belt.

which is preferably received This arrangement v permits the vibration ofthe plate |0 and its attached mechanism to occur without impairing thedriving connection rbetween, this mechanism and the comparativelyimmovable motor. The bottom of the gear-box is completed by a sheetmetal can |60 attached to the flange 3| and made imperforate so as tohold lubricating oil. 1

In the modification shown in Figs. to 13, the container is maintainedconstantly at a sufficient height above the bottom of the casing toenable the entire liquid contents to be received therebeneath. In thisembodiment of my invention I have shown the hub 53L of the container assleeved directly upon the upper end of the shaft 44, and as seated, atleast when in washing position, directly on the upper end of the sleeve40. Integral with this sleeve is a frusto-conical flange 54 as before,excepting that a hollow, annular, upwardly-facing recess |65 is formedbetween this sleeve and .the Aupper end of this flange. The containercomprises a sheet metal bottom 55a, tightly secured to this ange andmerging with an outwardly and upwardly projecting side Wall 52a asbefore, excepting that these walls are substantially or entirelyimperforate. At its upper margin the wall 52e merges with the inwardlycurved ledge 56, this part being provided with liquid dischargeperforations. Secured to the interior of the wall 52 adjacent the ledge56 is a peripheral, external, upstanding, metal strip |66 in the loweredge of an annular, inwardly-bowed, splash-guard` |61.

The upper end of the shaft 44'L projects above the sleeve 40, and alsoabove the hub 63H. Its upper extremity 41 is made prismatic as before toenable the attachment of a dasher or agitator of any suitable shape andconstruction. The

' portion of the shaft which traverses the upper tom face of afrusto-conical plate |15 Acarried by the flange 54a and overhanging therecess |65. When the shaft 44a occupies its lowered position the teeth|13 and |14 are spaced apart, but upon slightly raising this shaft theshoulders defining the lower ends of the atted portions engagevtheflange |1| and Alift the connector |10 until the teeth |13 and |14become engaged, thus establishing driving connection between the shaftand container. .g i

For operative purposes this amount oi'I elevation is sufficient, but forcertain additional purposes, sometimes desirable, I have in Fig. l2,shown the shaft as elevated suilciently so that the engagement of theflange |12 and plate |15 raises the hub 53 slightly above the end of thesleeve 4|). This ,elevation I utilize for the .purpose of employing abrake by which to arrest the rotational movement' of the container.'I'his brake, in its present form comprises an internally threadedcollar |80 screwed on the upper end of the sleeve 40 and surrounded bythree circular coaxial, metal plates IBI, separated by friction-disks|32.l The outermost plates are secured in place by flanges |33 carriedby the collar |80, while the midmost plate is extended beyond the othersand formed with upwardly projecting fingers |84 adapted, when thecontainer`v is lowered, to engage suitable spokes |95 projecting fromthe hub 53` (see Fig. these spokes swinging freely over the tops ofthese fingers when the container is raised as shown in Fig. 12.' z

The elevation of this container is so small (when it is elevated atall), as not to require the power-operated elevating devices heretoforedescribed, wherefore a simplified mechanism is employed as shown inFigs. `10 to 13 inclusive. The lower end of the shaft 4l is, as before,surrounded by a freely rotatable pinion 19*l supportedat a fixed heightby a bracket 11 as heretofore described, excepting that said bracket,instead of being rigidly mounted, is backed up by suitable coil springs|90, and that a ball-bearing |9| is interposed between said pinion andthe bottom of said bracket. Carried by the lower end of the shaft l is asecond pinion 94, here rigidly secured to said shaft. The adjacent facesof these pinions are provided with the cooperating members |92 and |93of a conical-clutch, so that when the pinion9|l and shaft are elevated,the rapid rotation of the pinion may be communicated gradually to theshaft without shock. This movement is eiected by means of a lever H3carried by the shaft II28L journaled in the side wall of thegear-housing and provided at its inner end with an arm |95 connected bya link |96 with a supporting lever |91 whose opposite end is pivoted ,at|99 to the vertically adjustable stud |99, and whose middle carries thethrust bearing 200 on which the shaft 44a rests. Even though the entirecontainer with its liquid load is elevated, th elevation is very slightand only occurs during the latter part of the movementv of the handlever, while the arm |95 is moving from position a to position b (shownin dotted lines in Fig. l1) The vertical I movement of the shaft l fromthe position shown in Fig. 10 to that shown in Fig'. 11 entails a largeangular movement of the lever which requires comparatively littleeffort, and terminates with the arm slightlybeyond dead-center whichprevents accidental descent of the ycontainer. Only when this shaftnears the upper limit of this movement is the weight of the containerimposed thereon, and at this time the angle between the link |95 and thearm |95 is such that the load can easily be lifted. The

mechanism is, a's before, driven by the horizontal drive-shaft 19*ifurnished with two spiral-gears or worms, one of which, 18, mesheswiththe pinion 15a, while the other, 85, meshes with the gear 84a whichis connected by the pitman B8 with the swinging sector 92'L meshing withthe pinion 94a. A comparatively shallow oil-pan |60* serves to housethis-gearing owing to the comparatively small vertical movement.

With the form of machine shown in Figs. l0

to 13 a pump is preferably provided for the purpose of elevating thewashing liquid into the container, either continuously during thewashing container or to deliver it at any desired place-of discharge.

The purpose of the shield |61 is to reduce loss of liquid from thecontainer by slopping during the washing operation. It is removed duringvthe extracting peration. Its use reduces the need forl` employing apump during the washing operation, and ishence particularly desirable inconnection with dry-cleaning uid which is either inflammable orexpensive.

The fact that I have illustrated and described my improvements withconsiderable detail is induced by my desire to comply with the statutein setting forth thebest mode of applying the' principles of myinvention and should not be taken as an indication that I limit myselfto any of the features of construction, arrangement, or design thereinshown, since I have illustrated divergent forms as an indication of myintent not to be so limited; and I do not restrict myself to any detailsshown except as specifically set forth in my several claims which Idesire may be construed broadly, each independently of limitationscontained in other claims.
